One of the fundamental concepts of marine ecology and modern fisheries management is that fish and other ocean wildlife need various types of habitat to feed, grow, and reproduce. Healthy ocean habitat is crucial to the well-being of ocean ecosystems and also provides spawning grounds for commercially important groundfish. New England’s ocean waters are home to several special places that deserve permanent protection.

Cashes Ledge, an underwater mountain range 80 miles off the coast of Maine, supports the largest and deepest kelp forest off the Northeastern United States and is home to an enormous diversity of ocean wildlife – from whales, Atlantic wolffish, and blue sharks, to fields of anemones and sponges. This kelp forest provides an important source of food and habitat for a vast array of ocean wildlife. Other places such as Jeffreys Ledge and Stellwagen Bank National Marine Sanctuary provide rich habitat for highly depleted cod and haddock, sea turtles, and four species of whales.

Most of these three areas in the Gulf of Maine currently benefit from fishing regulations which prohibit harmful bottom trawling, but these protections are temporary. Some of the largest commercial fishing trawlers in the region are pushing for changes in regulations to allow bottom trawling in Cashes Ledge, Jeffreys Ledge and the only protected portion of Stellwagen Bank National Marine Sanctuary.

After the last cod crisis in the 1990s the New England Fishery Management Council (NEFMC), after a court decree spurred by a CLF legal action, designated Cashes Ledge and an area known as the “Western Gulf of Maine” which holds Jeffreys Ledge and 22% of Stellwagen Bank National Marine Sanctuary, as “mortality closures.” The action restricted destructive trawling, but it allowed a wide array of other commercial fishing gear such as bottom gillnets, purse seines, hook and line and more the questionable practice of “mid-water trawls,” which despite their name, often catch groundfish. Recreational fishing and charter boats were not restricted.

This single protective measure restricting commercial bottom trawling helped to restore seriously depleted populations in these areas. Moreover, protecting areas like Cashes Ledge created the “spillover effect” where larger populations of fish migrate out of the boundaries of the protected area. This is why commercial fishing vessels often “fish the borders” of protected areas.

After a new stock assessment released one year ago showed that populations of cod, haddock and other groundfish were at all time lows, the National Marine Fisheries Service (NMFS) under pressure from some of the largest trawlers in the New England fleet started to hint that allowing bottom trawling in previously protected habitat areas – places like Cashes Ledge – might help to increase falling harvest amounts. At a time of the lowest recorded groundfish populations in history, how does it make sense to increase trawling in the best, remaining habitat areas?

This is why we must urge NOAA to keep our habitat protections in place.

Cashes Ledge is important not only to fish and ocean wildlife but also to scientists hoping to learn about the health and function of New England’s oceans. Many scientists believe that Cashes Ledge represents the best remaining example of an undisturbed Gulf of Maine ecosystem and have used Cashes Ledge as an underwater laboratory to which they have compared more degraded habitat in the Gulf of Maine.

The basic fact is that opening scarce protected habitat in the Gulf of Maine to bottom trawling at a time of historically low groundfish populations is among the worst ideas for recovering fish populations and the industry which depend upon them. But fisheries politics in New England remain. On Dec. 20^th the NEFMC may take action through a backdoor exemption process to allow bottom trawling in a large portion of Cashes Ledge and other areas. NOAA needs to keep current protections in place. CLF is committed to securing permanent protection to ensure the long-term health of this important and vulnerable ecosystem. Click here to urge NOAA to protect New England ocean habitat and help ensure a healthy future for New England’s ocean.

On the occasion of World Oceans Day, it is worth reminding ourselves about how utterly dependent we are on the ocean – for the fish and shellfish that grace our dinner tables, for our summer recreation – on, in, and alongside our ocean – for the tremendous untapped renewable resources of the wind, waves and tides, and for transportation of people and goods. Oh yes, and the air – up to 70% of the oxygen we breathe is produced by the plankton in the ocean. That’s more than from all the world’s rain forests combined. The ocean absorbs about half of our carbon dioxide emissions and over 90% of the heat trapped by greenhouse gases. The ocean covers 70% of our planet and regulates the earth’s climate. Unfortunately the ocean is facing a host of troubles from climate change and acidification caused by all that carbon dioxide absorption, not to mention overfishing, seafloor habitat destruction and pollution – we need to be better stewards of this incredible resource.

As I walked on Crane Beach last weekend thinking about all of this, an early summer Northeaster whipped the ocean into a froth and unusually high tides threw up a wrack line of seaweed reaching as far as the wind sculpted sand dunes – leaving just a sliver of a beach. I was reminded that the ocean truly is the master and commander, and once again I felt humbled by the sea’s strength and beauty. I was also a little frustrated by it. Why? Brian Skerry, weather permitting, will go on his first ever dive to one of New England’s most special places – Cashes Ledge –  this Saturday and Sunday.

Cashes Ledge, located 80 miles northeast of Gloucester, Massachusetts, is a 25-mile long underwater mountain chain that hosts one of the most unique, dynamic and ecologically productive areas in the Gulf of Maine. The highest peak, Ammen Rock, rises steeply off the ocean floor from 460 feet below to within 40 feet of the ocean’s surface.  There is an unbelievable diversity of ocean wildlife in this special place: North Atlantic right whales, blue sharks, bluefin tuna, herring, cod, Atlantic wolffish, sea anemones, brittle stars, brilliantly colored sea sponges, and the deepest kelp forest in the Gulf of Maine. But most of us have never seen this underwater jewel and probably never will. Unless, that is, someone goes diving and brings back spectacular photographs.

Brian’s planned dive on Cashes is just one of the many that he will be doing as part of the New England Ocean Odyssey – our 5 year partnership to bring to light the magnificent beauty that lies beneath the surface of New England’s waves. Despite all that we know about the ocean and its role in our lives, it still holds tremendous mystery. And I am happy for some mystery in these days of ceaseless information flow coming over our personal transoms 24/7 through our computers and smart phones. There is still so much we don’t know about the ocean and so much we can’t see. So gazing out to sea on that cold windy day, I wondered about what lies beneath the surface of those wild waves. My curiosity will soon be bated – at least for one special place in the Gulf of Maine.

With any luck Brian will show us just what a magnificent place Cashes Ledge is. I say with any luck, because, well, the weather has been challenging as of late. I have been electronically tethered to the Cashes Ledge weather buoy – a remarkable device that sends hourly reports on the wind, waves, water and air temperature, atmospheric pressure – hoping it brings us good news!

At the height of this week’s Northeaster sustained wind speeds at the buoy reached 25 knots with gusts up to 35 knots. And the waves reached nearly 14 feet.  Not good for diving!  But the weather seems to be moderating and we are hopeful that Brian and his dive crew will make it out to Cashes this weekend. If not this weekend, he’ll get out on another. And I can’t wait to share his photographs with you!  So today, on World Oceans Day, make sure you take the opportunity to thank our oceans for the mystery they still hold and for all that they do for each of us.
